Gnuradio number of output items

I'm trying to display "number of items on the output stream" in the flowgraph.

Is there a way to access the function: block__nitems_written(unsigned int which_output) from the flowgraph?

So far I have tried "from gnuradio import gr" and then use gr.block__nitems_written(0) as a value in a variable. The error I get is:

module object has no attribute block__nitems_written.

I think I am not calling the function properly. Any help will be appreciated!

You're confusing things! That's not a property of a flow graph.

Each block has its own number of items that it's written to its output ports.

Hence, it's a method of gr.block, which you can only call with a block instance, i.e. typically as self.nitems_written(0) within a block's work method.
